Radial profiles obtained in the rims of the RX J0852.0−4622 SNR in the southeast (top) and the northwest (bottom) along the spectral extraction regions shown in Figs. 1, 4. In the southeast, the distance of the PWN from the front shock is represented by the dashed lines. The best-fit exponentially decreasing model in the downstream side of the shock is illustrated with the solid lines.
